64位windows 2003环境UNC部署权限设置

系统环境：

WEB服务器：
Windows 2003 CHS ENT x86 64位操作系统

IIS 6.0 设置32位兼容模式

FrameWork 1.1,2.0,3.0,3.5 sp1，建议不安装中文语言包。

域服务器：

Windows 2003 CHS ENT x86 64位操作系统

AD域

NAS存储：

支持AD

安全体系：

用AD域作为用户认证和web、nas之间访问认证。

设置步骤：

域服务器：

1.创建UNCUsers组，将来创建UNC用户都隶属于该组。

2.管理WEB服务器，将UNCUsers组加入WEB服务器中的IIS_WPG组。系统默认会对ASP.NET创建临时文件的目录必须权限赋予IIS_WPG组，所以当IIS进程执行用户为UNC用户时，需要将这类用户加入到IIS_WPG组。

2.1.避免出现"Unable to get the private bytes memory limit for the W3WP process. The ASP.NET cache will be unable to limit its memory use, which may lead to a process restart. Error: 0x80070005"错误。

2.2避免出现"The current identity (user) does not have write access to 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.

Exception Details: System.Web.HttpException: The current identity (DLS\unc01) does not have write access to 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'."

NAS存储：

1.加入AD域。

2.对存放网站文件的目录，至少赋予UNCUsers组读权限。

WEB服务器：

1.安装Framework。

2.设置IIS兼容32位模式

执行：cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1

3.针对网站需要ASP.NET版本以及32、64位模式，在对应的Framework文件夹内执行命令

aspnet_regiis.exe -i

在IIS->WEB扩展服务->ASP.NET v2.0.50727 (32-bit)检查是否存在。

4.允许ASP.NET v2.0.50727 (32-bit)

5.执行安全权限

针对UNC路径，执行ASP.NET代码执行权限设置：同样区分版本和32、64位模式

caspol.exe -m -ag 1 -url "file:////\\computername\sharename\*" FullTrust -exclusive on

避免错误：

6.将UNCUsers组添加到IIS_WPG组。

7.网站虚拟目录设置

虚拟目录-另一台计算机上的共享-连接为，设置之前创建的UNC域帐户。

8.如果有MVC应用，必须保证全局代码集中包含相应代码集，最好的方案就是安装一下安装包。

MVC错误详解

安装完fw3.5sp1后，未安装MVC的安装包，同时程序又是部署在域环境的UNC路径中，通常第一次访问时候，会发现网站能正常访问，但是没过多久，就不能访问了。提示以下错误：

分析后发现“FileLoadException”发生的原因在于，网站的映射中将.mvc映射给aspnet_isapi.dll(如下图)
